Method of recording information on record medium having data record
region and file management information record region
In a method of recording actual data of files on a write-once type record
medium such as an optical card under the control of file management
information including file name and cluster chain management information,
the file management information is first read out of a file management
information record region of the record medium, cluster chain management
information is formed in accordance with the file management information
and is stored in a record area which is provided separately from said
record medium, and then the actual data of a file is recorded in
successive clusters in the data record region of the record medium.
Further, a file name and a file length of the file and a head cluster
address of the actual data of the file are recorded on the record medium.
The cluster chain management information is formed on the basis of file
names, file lengths and head cluster addresses read out of the record
medium. It is no longer necessary to record the cluster chain management
information on the record medium, and therefore the data record region of
the record medium can be utilized optimally.
